UNITED STATES WILHELM SOHMITT, OF SCHWELM, GERMANY.

SPECIFICATION forming part of Letters Patent No. 680,442, dated August 13, 1901.

7 Application filed October 5. 1900. Serial No. 32,093. (No model.)

To all whom, it may concern.-

Be it known that I, WILHELM SCHMITT, a

' subject of His Majesty the Emperor of Germany, residing at Schwelm, in the Province of Westphalia, Germany, have invented a new and useful Improved Machine for the Manufacture of Cask-Like Vessels, of which the following is a full and clear specification.

This invention relates to an improved process or improved machinery, respectively, for producing metal vessels having the form of a cask drawn in the upper and under parts and swelling in the middle.

My invention is fully shown on the accompanying drawings, of which- Figure 1 is a vertical section of the machine; Fig. 2, a top view; Fig. 3, a side View, partly in section.

Like letters of reference indicate like parts in all the figures.

By the reference-letter a is marked the framing or bed of the machine, which is made of cast-iron and has fixed thereto on both sides two arms I), which form brackets c. In these brackets are loosely supported the ringshaped bodies d, so that they can turn, for which purpose they are provided on their outer face with a gear 6. In said gear mesh the pinions f, whichare keyed to a shaft g, that is journaled in the brackets h of said arms b. The shaft g is revolved by known means. In the inner sides of the bodies d, which is enlarged, fit two clamping-rings 11 t", by means of which a metal cylinder 7c is jammed. The rings it" are smaller than their brackets, so that they may be displaced. The cylinder 70 forms the working piece from which the cask is to be made. It consists .of sheetiron and may be wholly closed, as seen in Fig. 1, or open lengthwise, as seen in Fig. 2.

By means of the arrangement described the cylinder revolves with the necessary speed, its diameter corresponding to the diameter of the ends of the cask to be produced.

The bed (it carries at its upper face a slidehead Z, which has a curved form, as will be best seen from Fig. 2. On the slide-head is mounted the rest on, from which extend the arms '17., forming brackets for the shaft 0, on which is keyed a roller 19. The arms I) have other brackets g, by which is supported a counter-roller q, being curved inward and corresponding in form exactly with the outlines of the slide-head Z. Now when being moved in axial direction the rest 17?. follows the slide-head and travels in the curved line,

and the tool p following is pressed against the inner face of the cylinder, pressing its material against the counter-roller and bellying it out, so that a cask is formed when the roller has passed along the cylinder. During this operation the working piece is allowed to adjust itself lengthwise.

What I claim is- In a machine for making cask-like vessels from a sheet-iron cylinder the combination of a bed having a curved slide-head, a rest to travel on it carrying the working roller, bearings fixed to the bed, ringshaped pieces turned in said bearings, a suitable gear to revolve said pieces and clamping-rings fitted in said pieces for the purpose described and set forth.
